The only thing that remains (and this was an issue right after the recap, before the regulator broke down) is that when adjusting the horizontal position, the screen jumps down a few lines when in a specific part of the adjustment range. I also notice a bent pattern in the upper corners.

Also, under certain circumstances (a specific program running with specific screen contents), the screen jumps down like a half a screen. The jump happens only once, the screen stays stable in the new position until I close the program (GFA basic with a specific source code loaded). Very strange isn't it?

I've looked at the adjustment instructions in the service manual but I can't seem to find anything that helps. I don't a have a pattern generator so I can't perform all of the instructions, sadly.

I can image that the replaced caps caused an unbalance somewhere that needs to be corrected.
